Description
Technical Field
The invention relates to the technical field of electronic paper, in particular to a handwriting type electronic paper display and a manufacturing method thereof.
Background
An electronic paper display is a display device driven by an electric field, and materials for display are mainly "electronic ink" and "microcapsules". Electronic ink is a liquid that can be printed or applied to any carrier surface, and originally consists of very tiny particles of black and white suspended in a transparent liquid. The microcapsule technology is to wrap the electronic ink in the microcapsule, thereby solving the aggregation problem of pigment particles.
These encapsulated particles, which inject electronic ink, carry a charge, the white particles carry a positive charge, and the black particles carry a negative charge. When a negative electric field is applied above the transparent electrode plate, the white particles with positive charges are attracted to the transparent electrode plate under the action of the electric field, and are gathered at the transparent electrode plate, so that the white color is displayed at the transparent electrode plate, and meanwhile, the black particles with negative charges are repelled to the bottom electrode under the action of the electric field and are hidden. When a positive electric field is applied to the transparent electrode plate, the black particles and the white particles move in opposite directions, which is the basic principle of the electronic paper display.
There are two main ways to control the movement of black and white particles in an electronic paper display: an electronic paper recording device supplies power to electronic paper through an electromagnetic induction unit and establishes communication connection with the electronic paper, when a handwriting input operation is performed on the electronic paper by using an electronic pen, the coordinate of an input position of the pen is detected, and vector data corresponding to the coordinate track is sent to the electronic paper as display data to be displayed; the electronic paper display is provided with a touch screen and a driving circuit, and the electronic paper display is driven to perform corresponding display by detecting the touched position of the touch screen through the driving circuit.
In summary, the conventional electronic paper display realizes electronic paper display control through electromagnetic induction or complex circuit processing, has a complex structure and high cost, wastes electric energy, and cannot meet the development requirements of energy conservation and environmental protection of the electronic paper display.
